CHARLES BAUGHMAN, OF NORTH WHITEHALL, PENNSYLVANIA.

MACHINE FOR BREAKING HIDES.

Specification of Letters Patent No. 7,281, dated April 16, 1850.

To all whom t may concern:

Be it known that I, CHARLES BAUCHMAN, of North Ihitehall, in the countyof Lehigh and State of Pennsylvania, have invented certain new anduseful Improvements in Machines for Working Hides and Scouring Leather;and I do hereby declare that the following is a full, clear, and exactdescription of my invention7 reference being had to the accompanyingdrawing, which forms part of this specification and which represents aview in perspective of my machine.

My hide breaking and scouring mill consists of a series of cylindersrevolving above a vat or cistern; each cylinder is furnished with abeater which is alternately raised and allowed to fall upon the barrelof the cylinder' beneath it, the latter is studded with blunt pins orbosses and the face of the beater is studded with similar pins which`correspond in position with the spaces between those on the cylinders;the cylinders also are arranged with respect to each other c, a, a, ofthree cylinders C, C, C2, one

gudgeon of each cylinder is prolonged beyond its bearing and isfurnished with a beveled wheel which gears into a beveled pinion csecured to a driving shaft D which crosses the frame at right angles tothe axes of the cylinders. The beveled wheels and pinions of eachcylinder are of equal size so that the three are turned with equalvelocit-ies. Immediately above the cylinders are the beaters E, E', E2,each of these consists of a heavy beam hinged at one extremity Z to astandard e erected on the frame and fitted at the opposite extremitywith a bray f which is acted upon by pins or tappets i projected from acam ring G secured to a shaft H parallel with the driving shaft- D, butat the opposite side of the frame. This cam-shaft is put in motion fromone of the cylinders C by a pair of beveled wheels g, g, one of which(g) is secured to the shaft and the other (g) to the gudgeon of thecylinder which is prolonged beyond its box for thatpurpose. The pins iin the several cam rings Gr, G, Gr, are arranged in such manner that thethree beat-v ers are raised and allowed to fall in regular succession,and the beaters are-guided in a vertical direction by guides L, 7L h2,secured to the frame. The barrels of the cylinders and the faces of thebeaters are studded with bosses or blunt pins 7c, 70, le, 7c, which areso arranged that those of the beaters fall between those of thecylinders with which they act, while those of each cylinder fall betweenthose of the one next to it.

The mill thus constructed may be used foi breaking or softening hides,for working out the lime or the bate, and for scouring the tanned hides.Theihides to be acted upon are tied together, so as to form an endlessbelt which is supported on the cylinders and hangs down into the vatbeneath, the latter is filled with water which should be changed asoften as it becomes foul. The cylinders are put in motion by theapplication of horse or other power to the driving shaft D; as theyrevolve they carry the hides in endless succession beneath the beaterswhich are raised by the pins t' and allowed to fall by their weight uponthe hides passing beneath which are thus beaten and worked by the bossesas they rise from the water at one extremity of the vat and pass into itagain at the opposite extremity. After the hides have been properlysoftened, they are limed in t-he usual manner and again subjected to theaction of the mill which will wash them clean. The mill may also be usedwith advant-age to work out the bate before the hides are subjected tothe tanning liquor. After the tanning is completed the leather may againbe placed on the mill, which will scour the hides and remove thediscoloration resulting from the use of black-oak or inferior bark inthe preparation of the tanning liquor, thus leaving the hides of auniform color throughout and greatly improvingtheir appearance.

Having thus far described my mill as composed of three cylinders withtheir appropriate beaters but I do not limit myself to this precisenumber but intend to use one or more as circumstances may renderexpedient.

That I claim as my invention and desire to secure by Letters Patent is-The breaking of hides, the working out of the lime and the bate and thescour ing of the tanned hides by means of revolv CHARLES BAUCHMAN.
